Rockstar held a presentation behind closed doors at the GamesCom convention at Cologne last week. The main focus was their titles planned for fiscal 2009, including The Ballad of Gay Tony, GTA: Chinatown Wars PSP, and Red Dead Redemption, which are under embargo until September 22.
However, they did mention L.A. Noire, specifically reinforcing that the title was still under development.
